Ok,I just baught a new z400 and I am looking to put some upgrades on it but want some feedback from others before i buy anything. I am thinking about putting a Trinity racing stage IV exhaust system on it, Dyno-Jet jet kit, Pro-Flow air filter and some aluminum OMF radiator scoops for looks.Please let me know if these mods will make this Z scream or not? Thanks for any and all help. Oh,and will those hotcams make any difference combined with the setup I'm thinking about going with?

Thanks

 

Definetly get the pipe, filter, and jets. You won't believe the difference. Then if you want more power, go with the Hotcam Intake Cam for some extra mid-top end power. Good luck.

 

I've heard the trinity pipe is a good one but it is a bit loud and it might not have a spark arrestor for if you want to fide on public trails. The pro circuit pipe won the dirtwheels pipe shootout.

 

I thought the CT pipe won it?

 

The gave a tie to PC and CT. Don't always listen to everything Dirt Wheels says though. Granted some pipes may be a little better than others, but not a huge amount. Also, it was obvious that some pipes were jetted incorrectly which hindered their dyno reults and could be improved on.

 

I don't own a z400 so I don't have any first hand experience, but I've found that dirt wheels gives pretty reliable advice for most things. The thing that I like is that they take other things into acount besides power, like noise. Anyways, I'd say whatever you get would work well. A four stroke doesn't need quite the same amount of fine tuning as a two stroke.

 

I would also get a rev kit, when I got one I my van it made it rev alot higher.
